US Classification:

210748, 210243, 210521, 204571, 204573, 204668, 205757

Abstract:

A method and apparatus for the high-pressure electrocoagulative treatment of aqueous and viscous fluids and sludge is provided. The apparatus includes a plate and frame design utilizing mechanical closure on a plurality of recessed, gasketed, non-electrically conductive electrocoagulation spacer plates that completely enclose and isolate all fluids, electrical contacts, and electrodes within the confines of the apparatus. The spacer plates include intergral supports that position and support said plates with enclosed electrodes on top of the side rails of the supporting frame of the apparatus allowing said plates to be separated for electrode replacement and maintenance and conversly closed, pressured and put into service. The apparatus includes a baffled influent and effluent chamber at both ends for the addition and flash mixing of chemical reagents and/or flocculants and to provide a means of fluid communication between fluid conduits and chambers formed within the apparatus.

Appl. No.:

11/105694

Inventors:

Kenneth H. Ward - Pearson MI, US
David J. Otto - Lake Orion MI, US

Assignee:

Nicholas Plastics Incorporated - Allendale MI

International Classification:

B60J 5/00

US Classification:

2961467, 296 108

Abstract:

A vehicle trim panel is secured to a vehicle structural panel by providing a vehicle trim fastener having spaced arms which embrace and overlie the legs on a mount which is seated over the edge of a vehicle structural panel. The embracing arms and corresponding legs prevent lateral shifting of the trim panel relative to the structural panel.

Appl. No.:

10/948906

Inventors:

David Otto - Lake Orion MI, US

Assignee:

JS Chamberlain & Associates, Inc. - Troy MI

International Classification:

E04C 2/00

US Classification:

052232000

Abstract:

A baffle apparatus mountable in a hollow structural member includes first and second sealed containers, each containing a separate reactive component. The first and second containers are formed of complementary melting point materials so as to melt and allow the reactive components to mix and react when the thermal energy is applied to the structural member. The reactive components form an expanded volume foam mass substantially filling, sealing, and/or reinforcing the cross section of the structural member.

Appl. No.:

12/992297

Inventors:

David J. Otto - Lake Orion MI, US
Clayton Raybourn - South Lyon MI, US
Mark Jurcak - Harrison Township MI, US

International Classification:

B32B 38/04

US Classification:

156261, 156391

Abstract:

A tool and method applies a cover to an item receiving face. A base plate has an item receiving surface. A moveable lower plate has a die bore corresponding to the cover receiving surface of the item and a receiving surface for a laminate cover material having an adhesive layer and a decorative base layer. An upper plate includes a channel corresponding with the lower plate die and a punch secured within the upper plate channel and slideably engageable within the die. The punch has a centrally located bore and cutting edge. A compressible member disposed within the punch bore has a curvolinear free end. The upper plate is displaced towards the lower plate in a closed state to slidingly engage the punch within the die and the punch cutting edge punches out the cover while the compressible member presses the cut cover onto the item receiving face.

International Classification:

B65D 8842

US Classification:

220221

Abstract:

A shoe seal for sealing the space between a floating roof and the inner wall of an oil storage tank includes a plurality of scissors hanger assemblies for movably mounting a shoe on the floating roof. Each scissors hanger assembly includes an elongated plate suspended from a shoe clip bolted to the shoe and pivotally coupled to an opposite pair of elongated bars suspended from a rim clip bolted to the outer rim of the floating roof. In a first embodiment, the shoe is resiliently biased into contact with the inner tank wall by pusher bars bolted to the shoe and having resilient legs extending into contact with the floating roof, and pusher plates bolted to the roof and having a resilient leg extending into contact with the shoe. In a second embodiment, only the pusher bars are used and they are mounted on the rim clips bolted to the floating roof so that the opposite resilient legs thereof extend into contact with the shoe. A vapor barrier fabric extends between and is joined to the shoe and to the floating roof to complete the shoe seal.

Assignee:

SIKA Corporation - Southfield MI

International Classification:

B32B 500

US Classification:

428 98

Abstract:

An expandable baffle apparatus for sealing a cavity of an automobile or the like includes a piece of heat expandable sealing material that is formed in a shape corresponding to the shape of the cross section of the cavity to be sealed. A support element supports the piece of sealing material at the predetermined cross section while the apparatus is subjected to an elevated activation temperature at which the sealing material expands to seal the cavity at the cross section. The support element is formed of a material having a melting point higher than the activation temperature, and includes an open lattice formed of a shape corresponding to the shape of the cross section of the cavity. The sealing material is supported on the lattice so that when the sealing material is activated, the material expands radially to fill the cross section of the cavity and longitudinally through the lattice.
